We set out in the Trident project to create a metadata tool that scales. In doing so we have conceived of the metadata application profile, a profile which provides instructions for software on how to edit metadata. We have built a set of web services and some web-based tools for editing metadata. The metadata application profile allows these tools to extend across different metadata schemes, and allows for different rules to be established for editing items of different collections. Some features of the tools include integration with authority lists, auto-complete fields, validation and clean integration of batch editing with Excel. I know, I know, Excel, but in the right hands, this is a powerful tool for cleanup and batch editing. In this talk, we want to introduce the concepts of the metadata application profile, and gather feedback on its merits, as well as demonstrate some of the tools we have developed and how they work together to manage the metadata in our Fedora repository.
